Hosted agent runtime

4RGED Cloud

Queue real engineering work — refactors, audits, migrations, fixes — and let it run in the cloud while you stay in flow. Every grep, edit, and test streams back. Every diff waits for your review.

Clean room every run

Fresh sandbox, zero memory of the last task. What ran yesterday cannot leak into today’s work.

Trigger on your terms

Merge to main, open a PR, hit a webhook, or fire on cron. Agents show up when the event does.

Steer from the browser

Read the run, redirect the agent, kill a bad path — no local clone, no VPN gymnastics.

Watch it think

Grep, edit, test, commit — streamed live. Not a summary dropped in Slack three hours later.

Nothing lost

Diffs, logs, and outputs saved on every run. Review today or download six months from now.

Many agents, one policy

Parallel runs across repos and teams, capped and governed by rules your security team can read.

Add rate limiting to unprotected API routes

Audit all API endpoints for missing rate limiting and add protection where needed

Checked out branch feat/rate-limit-audit

Found 23 unprotected endpoints across users, admin, webhooks, and billing. Creating shared middleware and patching sensitive routes.

import rateLimit from 'express-rate-limit';
export const rateLimiter = rateLimit({
windowMs: 15 * 60 * 1000, max: 100,
standardHeaders: true, legacyHeaders: false,
});
export const strictRateLimiter = rateLimit({
windowMs: 60 * 60 * 1000, max: 10,
keyGenerator: (req) => req.ip ?? 'unknown',
});

Applied strict limiters to password-reset, email-verification, and magic-link routes:

import { strictRateLimiter } from '../middleware/rate-limit';
router.post('/reset-password', strictRateLimiter, UserController.resetPassword);
router.post('/verify-email', strictRateLimiter, UserController.verifyEmail);
router.post('/magic-link', strictRateLimiter, AuthController.sendMagicLink);

Run the route tests, lint, and commit if everything passes

Rate limiting added to 23 unprotected endpoints across 4 route files and 2 middleware modules. All 31 tests pass, lint is clean. Branch feat/rate-limit-audit is ready for review.

use cases

Issue triage & fixes

Watch

Greps, edits, terminal output, and reasoning — streamed live, nothing off-screen.

Open any run and see what you would at your desk: the conversation, the terminal, the git history, the failing test — then steer it before it goes further down the wrong path.

Issue triage and bug fixing

Vulnerability remediation

auto

Repo, tools, branch rules, instructions — scoped before the sandbox boots.

Dependency sweeps, schema migrations, lint passes — wired to merge events or cron so the boring work stops competing for your Friday afternoon.

Migrations & refactors

Spin up

Repo, tools, branch rules, instructions — scoped before the sandbox boots.

Multi-file changes that need an hour of agent time, not an hour of your calendar. Start it, walk away, review the branch when it is ready.

Code migrations and refactors

New feature development

Nudge

Bad assumption? Jump in while context is hot — not after an hour of wrong work.

Same runtime as IDE and CLI

Models, prompts, tools, and policy travel with you — Cloud is just the hosted lane, not a different product.

Integrations

Connect GitHub, wire repo events, and hand off to the same models, prompts, and tools you use in the IDE and CLI.

Isolated cloud sandbox

Agents execute in an isolated environment with the repositories, secrets, and network access your organization allows — a consistent Linux runtime regardless of your local OS.
